I got myself a pb at 4:05, knocked 4 minutes off nearly from my last marathon. . Very happy with that. Was a bit emotional when I crossed under the Brandeburg Gate, just a brilliant moment for me.
I managed to keep with the 4:00 pacer up until 18th mile but I decided not to keep up with him after that because I was feeling a bit wobbly. The bananas was a superb idea, really gave me a boost. Not sure about the warm tea though.
The only negatives of the course was the crowded watering stations, could be stressful. I didn't particularly like the idea of handing the finisher t-shirts the day before, I thought that was not a good move by the organisers.
The expos' are a bit ridiculous though, some good stuff but a lot of 'snake oil' products and overpriced clothes. I did manage to pick up a hat for 5 euros.
Note: I stayed at the Hotel Gat Charlie and 50 yards down the road was all you can eat italian buffet. It wasn't not the best food but I did some major carb loading on Friday night for 11 euros.
